We have just joined and on clicking the month film pass we are told it expires on the 23d April?
Not much of a month more like a week??
Is this normal or a glitch, and nor does the chat function work.
Sounds to me that you have taken the free 7 day movie trial if you have just joined today the 16th of April and it also mentions the pass ends on the 23rd of April.
When you go to My Account > Passes & Vouchers on here and you click on the purple drop down arrow underneath your cinema pass what does it say (maybe post a screenshot on here).
Also if you purchased a month cinema pass it should show a payment of £11.99 under Bills & Payments taken on the 16th of April.
